Paper abstract
In this paper we investigate the use of DPCM compression for SAR raw data. We apply results from Wiener theory to analyze the statistics of SAR raw data. On the basis of this analysis, a DPCM-based compression algorithm named DPCM-BAQ is proposed. The performance of this algorithm is compared with that of BAQ, showing a significant improvement. Overall, in the cases considered, DPCM-BAQ achieves SNR in excess of up to 2.4 dB with respect to BAQ.
